Choose which of the following is correct regarding circular motion.

Circular motion is defined as the movement of an object along a circular path.

Centripetal force is a net force acting on an object moving in a circular path, with the force acting in the direction of the centre of curvature.

A circle is assumed to be a polygon with an infinite number of sides, each of which approximates to a point.

As a result, an object moving in a circular path changes direction at each point.

Because the direction changes at each point, so do the velocity.

Furthermore, because it is the force that causes a body to follow a curved path, a centripetal force always acts on an object in a circular motion.
